 Basic Concepts
 ==============
 
-.. important:: Distributed training is not officially supported as of version
-   |version|; however, some configuration options have worked for nGraph 
-   devices in testing environments.
-
-
-Data scientists with locally-scalable rack or cloud-based resources will likely
-find it worthwhile to experiment with different modes or variations of
-distributed training. Deployments using nGraph Library with supported backends
-can be configured to train with data parallelism and will soon work with model
-parallelism. Distributing workloads is increasingly important, as more data and
-bigger models mean the ability to :doc:`../core/constructing-graphs/distribute-train`
-work with larger and larger datasets, or to work with models having many layers
-that aren't designed to fit to a single device.
-
-Distributed training with data parallelism splits the data and each worker
-node has the same model; during each iteration, the gradients are aggregated
-across all workers with an op that performs "allreduce", and applied to update
-the weights.
-
-Using multiple machines helps to scale and speed up deep learning. With large 
-mini-batch training, one could train ResNet-50 with Imagenet-1k data to the
-*Top 5* classifier in minutes using thousands of CPU nodes. See
-`arxiv.org/abs/1709.05011`_.
